Impact and Application of Green Internet of Things in Various Fields

As we know, the concept of green computing is highly correlated to the environmental sustainability, eco-friendly computing and IT infrastructure. It comprises all the physical ventures and efforts that are environmentally safe technologies and biodegradable devices within the entire life cycle of ICT. The green computing terminology is mainly denoted as per the methodology adopted as a practice and study of not just using the computers and servers but also disposing them, which includes hardware devices like printers, monitors and storage devices etc. in order to reduce its impact to minimal level. The various electronic waste causes emissions of gases, e.g., carbon dioxide, methane and other gases, which can be hazardous to both humans and other natural creatures in the ecosystem. These emitted gases tear down the green and habitability factors within the environment while causing damage to the global climate.

Disposal of electronic waste is a major problem faced by many countries and thus scientific disposal of e-waste is necessary or else unscientific processing of e-waste recovery of metals can cause environmental pollution (Chatterjee, 2011). Here’s when Urban Mining comes into picture. Urban mining essentially refers to the practice of extracting precious and rare earth metals and energy from urban waste such as – e-waste and putting them back in the economy (Cossu et al., 2012; Bonifazi and Cossu 2013). Urban spaces can be considered as sources of anthropogenic materials that can be used in a cyclic manner, recycled, and reused (Brunner, 2011).

In the past 60 years, the electronic industry has known an outstanding evolution, which has a huge impact on everyday life. The appearance on the market of new products stimulates the consumers to buy new ones, leaving behind the “old” and technologically outdated ones. Electronic waste, (also known as “e-waste”) represents a worldwide problem that negatively affects the environment as a result of piling up a large amount of electrical devices, such as washing machines, refrigerators, computers, mobile phones, digital music recorders, electronic games, microwave ovens, smartwatches, televisions, etc. [1]. Another category of e-wastes is represented by housework items, namely out of use electronics, which after that they are brought in recycling centers where they can be reused, resale, or salvaged [1]. Therefore, it could be stated that even if electronic products make our life easier, they contain over 1000 different toxic compounds, like ferrous and non-ferrous metals, polymers, ceramics, which are irremediably polluting the planet [2]. Among these, half is represented by iron and steel; almost a quarter is given by plastics, followed in a smaller percent by ferrous metals [3]. Other e-waste materials that generate undesired effects, due to their toxicity and non-biodegradability, are mercury, cadmium, lead, selenium, and hexavalent chromium and flame retardants [4, 5].

The accumulation of electronic waste (e-waste) worldwide poses a severe threat to environmental health. Printed circuit boards (PCBs) are among the leading e-waste carriers among the different types of e-waste (Narayanasamy et al. 2018, 2020). PCBs consist of different metals of toxic and non-toxic groups, such as iron, copper, zinc, aluminum, lead, nickel, etc. (Arshadi and Mousavi 2015). Various physical and chemical methods have been employed for recycling or recovering precious metals from PCBs. However, these methods are expensive, destroy soil properties, and are limited to highly polluted environments and small-scale industries (Luo et al. 2015). Therefore, phytoremediation may provide an alternative to physical and chemical processes. Further, it has been reported that symbiotic interactions between plants and microbes for phytoextraction, phytostabilization, and phytovolatilization of various metals (Kartik et al. 2016; Jalali et al. 2020; Shreya et al. 2020).

Electrical and electronic waste (e-waste) comprises discarded mobile phones, computers, keyboards, televisions, printers, and other electrical and electronic devices. As of 2016, an aggregate of 44.7 million metric tons of electronic waste had been produced globally, which could be predicted to elevate as 52.2 million metric tons by 2021 with an annual growth rate of 3% to 4%. Further, India is generating the e-waste of around 8,00,000 tonnes annually. Also, the sudden rise of information technology industries has generated higher number of e-waste such as old computers and keyboards. According to the United Nations, e-waste from old computers will increase 400% in China and jump to 500% in India by 2020 (Garlapati 2016). Plastics are degraded gradually because of the molecular constituents of carbon, hydrogen, and some other components such as chlorine, and nitrogen. Regular dumping of plastics in the landfill would cause certain serious environmental problems.
Revisiting e-waste management practices in selected African countries

Electronic waste is defined as electrical and electronic equipment that have been discarded without the intent of re-use including all segments or sub-assemblies that are old, outdated, nonworking, broken and end-of-life (Kitila and Woldemikael 2019; Needhidasan, Samuel, and Chidambaram 2014; Step Initiative 2014). The term covers any appliance that no longer satisfies the current owner for its original purpose including both “white” goods (e.g. Refrigerators, washing machines, microwaves) and “brown” goods (e.g. televisions, radios, computers) that have reached their end-of-life (Khetriwal, Kraeuchi, and Widmer 2009; Sinha-Khetriwal, Kraeuchi, and Schwaninger 2005). E-waste may also include products that are fully functional but which no longer serve the needs of the original purchaser.
